In this study, we evaluate velocity of the tongue tip with magnetic resonance imaging (MRI) using two independent approaches. The first approach is by acquisition with a real-time technique in the mid-sagittal plane. Tracking of the tongue tip manually and with a computer vision method allows its trajectory to be found and the velocity to be calculated as the derivative of the coordinate. We also propose the use of another approach—phase contrast MRI—which enables velocities of the moving tissues to be measured directly. Simultaneous sound recording enabled us to find the relation between the movements and the sound. The results of both methods are in qualitative agreement and are consistent with other reviewer techniques used for evaluation of the tongue tip velocity. View this paper
